Description

A kind of pipe for osmotic irrigation

Technical field

The utility model belongs to agricultural irrigation water-carriage system technical field, is specifically related to a kind of pipe for osmotic irrigation that sub-irrigation is carried the water source that is used for.

Background technology

Infiltrating irrigation is a kind of underground water-saving irrigation method, and also the someone is referred to as underground drip irrigation.Have the advantage of significant water saving, energy-conservation, saving of labor, volume increase and raising product quality, and receive much concern.Its implementation method is a lot, roughly can be divided into two kinds of point type and line formulas, and point type (claiming the aperture formula again) is exactly with fluid-tight plastic tube water to be delivered to crop root, irrigates by a kind of head that oozes that is embedded in underground slowly water seepage then.Line formula (claiming full wall type again) is to adopt to be embedded in the underground pipeline that can slowly outwards seep water and directly to irrigate.It is comparatively extensive that line formula method is used, and its employed soakaway trench is divided into two kinds of antipriming pipe and microporous pipe again.Antipriming pipe is to beat a lot of apertures or long longitudinal joint on tube wall, and microporous pipe is the pipeline that pulls into special material (rubber that junked tire reclaims, plastics etc.), and countless foamed micropores are arranged on the tube wall.In pipe, will ooze out as perspiration gradually during water-filling, irrigate.

Each is variant for the situation of infiltration irrigation technology research and development both at home and abroad now, and large quantities of infiltrating irrigation tubing swarm out.

China takes porous to lose the water hollow billet more, a kind of is with waste old, plastic resin and additive, the rubber soakaway trench that process scientific method and special process are made, the hair shape permeable hole that is covered with tiny bending on the tube wall, during use, pipe internal pressure water oozes out along pore, around tube wall, form the moistening soil of water droplet, another kind is to make the low pressure feed water pipeline with PE, PVC or UPVC, with hole forming machine boring, the infiltration head is installed in the hole on pipeline.Feedwater piping can be laid and be placed on the ground, also can imbed soil layer.The rubber soakaway trench is stopped up by solia particle easily and biological the obstruction, and the low pressure feed water pipeline owing to adopt boring that the infiltration head is installed, is an a kind of some seepage mode then, needs certain installing space, and the carrying capacity that this has just reduced irrigated crop has influenced the uniformity of water delivery.

More external developed countries adopt method of all kinds to develop infiltrating irrigation tubing.The U.S. utilizes rubber that junked tire reclaims and polyethylene and additive that some are special, made novel porous infiltrating irrigation pipe through scientific formula and special processing technology (not being to add blowing agent and blowing agent), the permeable micropore of many tiny bendings distributes on the tube wall, under 0.1～0.2MPa pressure, water just oozes out from permeable micropore.But also have some problems at present, main problem is a silting, and through the analysis to the silting thing, the infiltration hole mainly is biological the obstruction except solia particle stops up.This is taked careful filtration in infiltrating irrigation pipe stem, all carried out high pressure washing before and after using, still, still can not solve biological blockage problem fully.This infiltrating irrigation mode is invested greatlyyer simultaneously, is generally four times of sprinkling irrigation.Check, keep in repair all cumbersome in addition.

The infiltrating irrigation Guan Ze that France produces adds blowing agent and forming agent mixing back extrusion molding by waste plastics (low density PE), is called the TURORZX pipe.Numerous blister micropore is arranged in the tube wall.When system water supply, glassware for drinking water has the tube wall of blister micropore to ooze out or along the superfine current of even tube wall ground ejection, the size of water percolating capacity and the infiltration uniformity depend primarily on the aperture of operating pressure, abscess and the uniformity of material.This tubing has certain anti-clogging performance, but pipe fitting is cavernous, and its mechanical strength can not get ensureing, when burying underground because the artificial origin easily forms discounting, phenomenons such as causing pipe fitting damage and aperture distortion fractures; Simultaneously, irrational pipe outflow that oozes also can cause irrigation water and the deep percolation phenomenon occurs.

Italy then adopts plastics side seam formula film tube, has capillary channel along pipeline.During use, pipe ends links to each other with feed pipe, is embedded in undergroundly, and velocity in pipes is very low.Make capillary channel open outside infiltration because of tube wall is subjected to internal water pressure during water supply, tension force disappears when cutting off the water, the capillary channel closure.Though anti-clogging and deep percolation more effectively, it needs bigger hydraulic pressure to irrigate, and for the production and development of agricultural, does not possess the favorable economic benefit advantage.

Announced a patent recently about Clogproof filtration irrigation composite tube buried ground, its characteristics are that this multiple tube is to be made of the water-supply-pipe of nexine and the unordered netted pipe of plastics and the outer field permeable layer in middle level, and water is progressively developed into the little to stream infiltrate journey of water in the hydrogeology in the infiltration process of infiltrating irrigation.The structure of this three-layer composite pipe has effectively prevented buried aqueduct by solia particle and biological blocking problem, but irrational pipe outflow that oozes can cause irrigation water and the deep percolation phenomenon occurs.The place that soil permeability is very big or ground line gradient is steeper all is not suitable for adopting this infiltration irrigation technology.

The utility model content

The technical problem that the utility model solves is to overcome the deficiencies in the prior art, a kind of antiseepage hole plug, anti-deep percolation is provided and has the pipe for osmotic irrigation of mechanical strength and independent water recharging ability preferably.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of pipe for osmotic irrigation is characterized in that, comprises the plastic conduit of internal layer and the plastic layer of outer alveolate texture, and described plastic conduit is provided with the infiltration aperture.Described infiltration aperture is that net distribution or strip distribute.The plastic cement of outer alveolate texture wraps the plastic conduit that internal layer is provided with the infiltration aperture, the infiltrating irrigation mode on plane is changed into three-dimensional saturating filling mode, change the water system seepage flow slight irrigation of 360 ° of three-dimensional scopes of alveolate texture plastic layer into by infiltration aperture drip irrigation, changed drip irrigation and the water delivery of slight irrigation mode in the past.The blocking portion zone even solid particle or biological growth are arranged; for the infiltration mode of outer plastic layer solid; this obviously is inappreciable; prevent to irrigate insufficient or even be the phenomenon that to irrigate thereby reached, and can be uniformly and effectively material be transported to each place of crop and crop everywhere because of obstruction brings.

Outer plastic layer adopts special process to process, and this plastic layer is a kind cotton matter, and hydrone is had certain adsorption capacity, and inside is alveolate texture, and hydrone is had support ability preferably.Possess enough mechanical strengths simultaneously.Since the material of outer plastic cement be a kind of hydrophilic substance simultaneously in conjunction with the particularity of its structure, hydrone is had better adsorption capability and support ability, even when carrying hydraulic pressure not enough, water also can infiltrate outer plastic layer easily, finishes irrigation smoothly.

The utility model course of work is as follows: after carrying the water source, water body flows to the plastic layer of outer alveolate texture from the infiltration aperture, and plastic cement can and be kept here a certain amount of moisture absorption.When water system breaks down or can not in time send water because of insufficient water sources, the continuous drain evaporation of moisture in the earth and become dry, the inner moisture content that pins of plastic layer is delivered to naturally again in the dry earth and goes, so just reach the moistening of maintenance earth, alleviate the damage caused by a drought of crop to a certain extent.In addition, when carrying the water source, traditional infiltrating irrigation tubing causes irrigation water and the deep percolation phenomenon occurs because the water source permeates on soil in a large number, and there is this problem in ground quadrate part very big in soil permeability or that ground line gradient is steeper.And the utility model is owing to the close attached power of plastic cement to hydrone, along with fed distance increases, carry hydraulic pressure constantly to reduce, when plastic cement is conducted oneself with dignity greater than water body to the absorption affinity of water, water body can be attracted on the plastic cement, and this has just prevented that the water source from continuing to have reduced the deep percolation phenomenon that causes owing to carrying capacity is improper to soil permeability, prevent the unnecessary waste of resource effectively, improved economic benefit.

Compared with prior art, the beneficial effect of technical solutions of the utility model is: at first, the utlity model has superior anti-blockage capability, can prevent that not only solid particle from stopping up the infiltration hole, also can solve biological blocking problem effectively.Secondly, the simple material-saving of the composite construction of two-layer equation, and outer cellular plastic layer has enough mechanical strengths, and not fragile.Once more, the utlity model has the existing not available hydrophilic characterization of adsorption of infiltrating irrigation tubing, can prevent deep percolation effectively, pin moisture, keep soil to be in moisture state for a long time, for crop provides a good growing environment.Simultaneously since outer plastic layer to the good adsorption ability and the support ability of water, even under the situation of low pressure laminar flow, the utility model is transportation of substances continuously and healthily still.In addition, even if water-carriage system is malfunctioning or because of other accidents, when causing the water source not to be transported to crop in time, the utility model also can will be stored in the moisture supply crop of plastic layer inside, save resource, reduced waste, played key effect in the time of critical the time.
